Statistics test examining whether SAM EFR amplitudes are different across subjects with or without impaired audiograms for stimulation at different presentation levels [dB SPL]
| SAM EFR level | ||
|---|---|---|
| [dB SPL ] | t(d.f.) | p |
| 60 | t(12) = 1.49 | p = .16 |
| 65 | t(13) = 1.20 | p = .29 |
| 70 | t(14) = 1.61 | p = .13 |
| 75 | t(15) = 0.67 | p = .50 |
| 80 | t(17) = 1.24 | p = .23 |
Results from independent t-tests conducted on the Encina-Llamas et al. (2017) dataset reporting EFR magnitudes to a 98-Hz SAM tone of 4,011 Hz and shown in Figure 8. All t-tests showed that the NH EFR amplitudes were not significantly different from the HI EFR amplitudes when presented at the same stimulus level. Only EFR amplitudes that were significantly above the noise floor were included for each stimulus level condition listed in the table.
